Hi Zac, Sorry for the delay, took more time than I expected. Anyways I tested everything, I think the topics and frame_ids are all fine, should be good to work! If you notice anything wrong let me know, I should now clean up the code and re-submit my patch :D I'll wait for some news from you first though, to make sure everything's ok this time! To run this version of stage just unzip the stack, place it under your ros stack path and do: $ rospack find new_stage $ rosmake new_stage $ roscore On a new terminal window/tab: $ roscd new_stage $ rosrun new_stage newstageros world/willow-roomba_ranger_laser.world This world file has 2 robots on the willow map, one with an array of sonars and another one with 2 lasers. I changed the names of the stack, pkg etc etc so there's no trouble with the installed version of simulator_stage. Also I added the Range msgs to that stage pkg just for testing since it isen't part of sensor_msgs yet. Hope this helps, Gonçalo Cabrita ISR - University of Coimbra Portugal On Fri, Dec 3, 2010 at 9:10 PM, zdydek wrote: > > Gonçalo, > > I was able to find a copy of your patch and played around a bit with it. > Nice work!
